The E.S.R. g²-tensors in CuSO₄,5H₂O

Abstract

The angular variation of the e.s.r. g-value of single crystals of CuSO₄,5H₂O has been measured in a number of crystal planes. With the assumption that the resonances for each of two independent tensors are symmetrically broadened, the data have been analysed to obtain all the elements of these two tensors. The low value of X (1.27) obtained for the fit to the data indicates that the values obtained for the elements are of worthwhile accuracy. The orientations of the axes of the tensorsin relationship to the Cu-O bond vectors confirm assumptions made in previous treatments. The largest axis of each tensor lies close to one of the Cu-O(SO₃) bond directions.
